Quoting Rabid Goldfish
Personally, I'd say give the pilot block a tilt instead of being fully vertical, and give it a gun emplacement and you've got a real winner here. The design is very inspired. You continue to astound me with your work. ^Blub^

I find it difficult to make something on LDD from scratch, but you seem to do amazingly well. I would only suggest to tilt the cockpit like Goldfish said. Other than that, wonderful job.

practice, that's all I can suggest. when I started my first few LDD projects were awful.
I find trying to recreate stuff you (or someone else) has made in real bricks, is a good way of developing techniques for LDD.
